The present invention relates to a rotary valve structure for internal combustion engines and has for its object to provide a structure which is simple, eliminates usual tappet valve troubles, valve grinding and the like, is noiseless in operation, is easily lubricated and is constructed so that the intake takes place through the same port that the exhaust takes place through so that the intake gases will benefit thereby and the structure will be cooled.

Another very important object of the in-- vention resides in the provision. of a valve structure of this nature which isdurable, compact, and thoroughly efficient and reliable in operation. 1

With the above and numerous other objects in view as will appear as the descriptionproceeds, the invention resides in certain novel features of construction, and in. the combination and arrangement of parts as will be hereinafter more fully described and claimed. I

In the drawings:

Figure 1 is a fragmentary vertical longitudinal section through an engine embodying thefeatures of this invention,

Figure 2 is a detail section therethrough taken substantially on the line 2-2 of Figure 1.

Referring to the drawing in detail'it will be seen that the engine block is provided with cylinders 8 having pistons 9 mounted therein in any well known manner. A hollow head 10 is mounted on the engine block across the top of the cylinders 8. Intake conduits 12 are mounted in the head 10 and extend through openings in the bottom thereof to communicate with the cylinders 8.

Exhaust conduits 11 are similarly mounted in the head 10. These conduits 11 and 12 are of an inverted L-shaped formation. Exhaust conduits 15 lead from one side of the head from the exhaust manifold to terminate opposite the terminals of the exhaust conduits 11 and intake conduits on the other side of the head and terminate opposite an alinement with the terminals of the conduits 12. V

Casings 16 are formed in the head 10 and provided in thecasing 16.

have caps 17 cletachably associated therewith to vextend above the head' 10. These casings and caps are'of an annular formation to rotatably receive disks 18 forming the valve having a hub portion 19 journaled in the upper wall of the block 10 having removable bearing caps 20 with their ends engaged thereover and journalling the shaft 21 to which th'e'hubs 19 are keyed in sliding fit.

The shaft 19 is driven by a sprocket mechanism from the crank shaft of the engine so that there will be one revolution of the shaft 21 to 4'of the crank shaft. The disks 18 are provided with ports 24 one hundred and eighty degrees apart adjacentthe periphery thereof for registration with the opposed terminal of conduits 11 and 15 and conduits 12 and 14 which terminals extend to openings The openings 24 are substantially triangular in shape as is clearly shown in Figure 2 so as to be capable of registering with the conduitso that the conduits 12 and 14 are located slightly above conduits ll'and 15. Oil is disposed in the head so that the lower portion of the disk fits therein as is clearly the head and then idles two degrees and then 7 passes the intake conduit in the head.

It will thus be seen that the exhaust gases heat up the ports and then the ports are cooled'by the intake gases thus keeping the disks at proper operating temperature.

Itis thought that the construction, operation and advantages of the invention will be quite apparent to those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely byway of example in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of itsadvanta es.

Having thus described our invention, w at we claim as new is:

In a valve structure for internal combustion engines comprising an engine head of hollow construction having casings extend-V ing transversely therein, intake and exhaust conduits leading to and extending from the casings, each casing comprising in c0nstruction a pair of spaced side walls, a disc valve operable within each casing, said disc having ports to register with the conduits, caps for disposition over the said casings and the upper portions of the said discs, a shaft on which said discs are mounted, and means for mounting the shaft.

In testimony whereof we affix our signatures.
